To maintain the quality of the feathers, birds regularly undergo moult. It is widely accepted that moult affects flight performance, but the specific aerodynamic consequences have received relatively little attention. Here we measured the components of aerodynamic drag from the wake behind a gliding jackdaw (Corvus monedula) at different stages of its natural wing moult. We found that span efficie
OBJECTIVES: Post-stroke cognitive impairment (PSCI) has considerable impact on patients and society. However, long-term studies on PSCI are scarce and may be influenced by assessment methods and selection bias. We aimed to (i) assess the prevalence of long-term PSCI; (ii) compare two common cognitive assessment instruments; and (iii) compare cognitive function of long-term stroke survivors with no
The article argues that the digitally mediated and data-driven development stresses the need for socio-legal scrutiny. It focuses and briefly outline socio-legally relevant aspects of the “sharing” economy, that poses a number of conceptual issues on how we understand and regulate innovative platform based ventures.

We focus and briefly outline socio-legally relevant aspects of the “sharing” economy, that poses a number of conceptual issues on how we understand and regulate innovative platform based ventures. This also arguably underscores a number of issues relating to the role of consumer and
The paper investigates the reduction of dynamic power for streaming applications yielded by asynchronous dataflow designs by using clock gating techniques. Streaming applications constitute a very broad class of computing algorithms in areas such as signal processing, digital media coding, cryptography, video analytics, network routing and packet processing and many others. The paper introduces a
The growing complexity of digital signal processing applications make a compelling case the use of high-level design and synthesis methodologies for the implementation on programmable logic devices and embedded processors. Past research has shown that, for complex systems, raising the level of abstraction of design stages does not necessarily come at a penalty in terms of performance or resource r
Dataflow programming is a paradigm for describing stream processing algorithms in a manner that naturally exposes their concurrency and makes the resulting programs readily implementable on highly parallel architectures. Dataflow programs are graph structured, with nodes representing computational kernels that process the data flowing over the edges. There are two major families of languages for t
A computer-implemented method of caching data in a managed runtime computing environment can include loading source data and comparing content of the source data with at least one of a plurality of cache entries. Each cache entry can include a representation of previously received source data and a transformation of the previously received source data. A transformation for the source data from a c
Pancreatic beta cell failure is the central event leading to diabetes. Beta cells share many phenotypic traits with neurons, and proper beta cell function relies on the activation of several neuronal-like transcription programs. Regulation of gene expression by alternative splicing plays a pivotal role in brain, where it affects neuronal development, function and disease. The role of alternative s

Action Plan B3 of the European Innovation Partnership on Active and Healthy Ageing (EIP on AHA) focuses on the integrated care of chronic diseases. Area 5 (Care Pathways) was initiated using chronic respiratory diseases as a model. The chronic respiratory disease action plan includes (1) AIRWAYS integrated care pathways (ICPs), (2) the joint initiative between the Reference site MACVIA-LR (Contre
This case study of development in a technical university situates distributed leadership in higher education in an organizational perspective. Analysis of documentation from development programs and interviews with 10 faculty members showed that leadership practices were related to different institutional logics prominent in four key activities in this specific university: education, research, for
Boken innehåller en grekisk text (baserad på cod. Athos Protaton 86) utgiven av Britt Dahlman och en svensk översättning av den systematiska samlingen av Apophthegmata Patrum (Ökenfädernas tänkespråk), bok 8. Översättningen har gjorts gemensamt av deltagarna i översättningsseminariet vid Johannesakademin.The book contains a Greek text (based on MS Athos Protaton 86) edited by Britt Dahlman and a Swedish translation of the Systematical collection of the Apophthegmata Patrum, book 8. The translation was made jointly by the participants in the translation seminar at Johannesakademin.
The changes in life-style with increased access of food and reduced physical activity have resulted in the global epidemic of obesity. Consequently, individuals with type 2 diabetes and cardiovascular disease have also escalated. A central organ in the development of diabetes is the pancreas, and more specifically the pancreatic beta cells within the islets of Langerhans. Beta cells have been assi
Goal of the project CARIBIC (Civil Aircraft for the Regular Investigation of the atmosphere Based on an Instrumented Container) is to carry out regular and detailed observations of atmospheric composition (particles and gases) at cruising altitudes of passenger aircraft, i.e. at 9-12km. Mercury has been measured since May 2005 by a modified Tekran instrument (Tekran Model 2537 A analyser, Tekran I
